The pumping station is designed for pumping heavy oil at densities not exceeding 1300 kg/m3 and temperatures not exceeding 200ºC. The pumped product viscosity ranges from 20 to 1000 cSt.
ErichHahn HPS Advantages
ErichHahn HPS pumping station models available. They have similar design and composition while differing from each other in terms of capacity, overall dimensions and components.

High Pumping Station | HPS
The pumping station is designed for pumping heavy oil at densities not exceeding 1300 kg/m3 and temperatures not exceeding 200ºC. The pumped product viscosity ranges from 20 to 1000 cSt.
The internal gear rotary pump is designed for heavy oil pumping. The pump ensures a uniform supply of pumped product without pulsations to reduce the vibration level of the pumping station, and product foaming. The pump has an integrated safety valve for overpressure protection.
The Operation panel of the control cabinet has controls and indicators of the unit’s status. The control cabinet connects to the central control cabinet for communication with the frequency converter. The control station is an integral part of the heavy oil supply pumping station. The controls on the Operation panel of the control cabinet are used to operate the pump startup and performance. The cabinet has indicators of key pump process parameters, power supply availability, and standby status of the pumping station.
The frequency converter controls the motor. The central control cabinet includes a frequency converter (it is outside the supply scope but still is an integral part of the plant). The control cabinet is connected with the central cabinet with multi-core cables.
The control cabinet supports local and remote control modes, and a control off mode. A three-way key switch of the control cabinet is used for switching the modes. In the local mode, operating is exercised from the control cabinet directly (the pump is started, and its performance is controlled using the controls located on the control cabinet door). The remote control mode allows the user to operate the pumping station remotely using the controller equipment and operator workstation depending on the configuration of the central I&C system of the enterprise. All control commands are ignored in the control off mode. All the control cabinets have pump drive service power shutdown switches for on-site power supply shutdown of the pump drive and safe maintenance of the pump.
Loading system provides loading of oil products from the storage into trucks. Loading system is equipped with a loading arm, pipelines, shut-off valves and instrumentations.
The pump and filter are heated with thermal oil heating system. All of the units are covered with high density thermal wool insulation and removable protective shells.
HPS Gear Motor
The gear motor transmits and converts the rotational motion to the gear pump via a flexible coupling. The frequency converter of the power equipment cabinet is designed for starting the pumping unit and changing its performance.
